Generally stated my invention consists of a frame adapted to be mountedon the ord1- narybaling chamber, which frame is pro vided with springsonv its upper side, which of said frame, thus giving to said frame a'vertical and longitudinal movement. The frame proper consistsof atelescoping frame and has mounted on eitherside a pair of needles sodesigned that when the frame is drawn outwardly by means of the plunger,

the needles will be driven across the frame I one pair on each side of ahead block. One pair carries the wires across for the new bale andmay betermed the threading needles, while the other pair carries the wiresacross the balingchamber from the opposite side into .the tyingmechanism for completing the old bale and may be termed the bindingneedles. The head block is providedwith pins designed to engage dogspivotally mounted on said frame by means of which the frame is set inmotion and causes an automatic means to connect with the plunger bymeans'of which plunger the telescoping frame is pulled outwardly,drawing the needles across the frame and carrying the wire therewith asexplained. After the frame has been pulled outwardly a predetermineddistance the means connecting with the plunger is automaticallydisengaged and the frame is drawn inwardly by means of a spring whichcauses the tying mechanism to operate, thus tying the ends of the wiresand completing the halo.

Referring to the drawings in detail, I .have used the reference numeral10 to'designate the baling chamber'as a whole, which may be of any ofthe ordinary constructions, and 1-1 designates the main frame of thebaling and tying mechanism which main frame is provided at its top andbottom with a telescoping frame but as the top and bottom arethe same, adescription of the top which is clearly shown in Fig. 4. will besuflicient for both. Pivotally mounted on the top of the frame 11substantially at its center are a pair'of arms 12 which arms arepivotally connected at their outer ends by means of a pair of shortdiverging links 13. Pivotally connected to the arms 12 are a second pairof links 14 which links are pivotally connected at their outer ends toanauxiliary frame 15 which auxiliary frame extends entirely around thebaling chamber. Mounted on the under side of the upper side of the frame11 are a pair of steel springs 16' to permit ofa vertical movement ofthe frame 11.

-' On the top and on the bottom of the baling chamber are suitable coilsprings 17, which are connected at one end to the frame 15, and at theiropposite ends to the main frame 11, for the purpose presently to bedescribed.

18 designates a chute through which the hay is fed into the balingchamber.

19 designates the head block which is provided with pins 20 which pinsare deslgned to travel in the grooves 21 in the balmg chamber but whereit is desired to use my invention with a baling chamber of the usualconstruction, that is, one without the grooves, I provide the head block19 with spring pins as best shown in Fig. 16. The head block is insertedin its place. The hay is then fed into the chamber through the chutewhich forces the head block longitudinally of the frame, the pins on thehead block traveling .in the grooves 21. After the head block has thusbeen moved longitudinally in the baling chamber sufliciently, the pinsengage the dogs 23 for a purpose presently to be described. Thedogs 23are arranged in pairs, two on each side one above the other and arepivotally connected to the frame 11 by any suitable means such as thepin shown, the upper dog being connected to the lower one by means of alink 23 as best shown in Fig. 9. At a point spaced apart from theconnection to said frame, said lower dogs are pivotally connected bymeans of a link 24 to one end of the link 24*. The said link 24 isprovided at its opposite end with a curved bearing shoulder, which endis pivotally connected to a suitable bracket 24. Said bracket is rigidlysecured to the main frame 11 by any suitable means. Pivotally connectedto the bracket 24 and the link 2-1 is an arm 24 which arm is provided atits upper end with a lug having a curved bearing shoulder designed toengage the curved bearing shoulder on the 'link 24, by means of whichthe links 24 and 24 are forced into the position shown in dotted linesin Fig. 9 when the arm 24 is forced forwardly. The lower end of the arm24 is bifurcated and is adapted to be engaged by the lug 26 on the rod27. The links 24 and 24" are provided with shoulders 24: designed toengage each other to prevent said links from being folded in but onedirection, thus preventing the dogs 23 from 'l')e'ing tripped until saidlinks are forced into the position shown in dotted'lines in Fig. 9.

lVe will call the end on which the chute 18 is mounted through which thehay is fed the rearward end and the opposite end the forwardend as bestshown in. Fig. 2. As the head block reaches the main frame 11 and thepins engage'the dogs 23 the ntire frame 11 is moved forwardly a shortdistance which allows the pivotally mounted dogs 32 tit Will

frame 11. by any suitable means. When the dogs 23 are engaged by thepins on the head block the main frame 11 is forced forwardly a shortdistance which causes the lugs 33 on the rods 34 to disengage the lugsthus allowing said dogs to be forced into engagement (through alongitudinal opening in the sides of the baling chamber) with thenotches in the plunger by means of coil springs 35. It will of course beunderstood that the plunger has a reciprocatory movement and as itstarts on its outward stroke it engages the dogs 32 (that is assuming ofcourse that they have been released as before stated), thus drawing theauxiliary frame 15 outwardly for a purpose presently to be described.After the tying and binding operation is completed and the dogs 23released the main frame 11 returns to its normal position by means ofthe compression springs 28 which springs are wound on the rods 28. Thesaid rods are rigidly secured at one end to the side of the main frame11 and slidably mounted at the opposite end in the brackets 29, thelatter end being provided with a nut to limit the rearward movement ofthe frame 11. The brackets 29 are rigidly secured to the side of thebaling chamber one on each side by any suitable means. The head block isheld in its proper position until after the needles (presently to bedescribed) are driven across the baling chamber and back to their normalposition. This is accomplished by means of the links 24 and 24 and thearm 24 heretofore described. After the binding and tying operation iscom leted it is necessary that the dogs 23 be tripped, thus releasingthe head block and allowing the frame 11 to be returned to its normalposition by means of the springs 28 above described. This ll accomplishby means of the rods 27 which are rigidly secured to the auxiliary frame15 on each side near the lower edge thereof, which rods extend forwardlypast the main frame 11 and are provided with a lug 26, but as theconstruction and operation of each are the same. a description of theoperation of one will be sufficient for both. As the auxiliary frame 11is drawn forwardly by means of the mechanism heretofore described, thelug 26 on the rod 27 forces the arm. 24 into the position shown indotted lines in Fig. 9, while the links 24 and 24 are in the positionshown in heavy lines in the same figure. The lug 26 is positioned on therod 27 so that it will slide past the bifurcated end of the arm 24",thus allowing said arm to return to the position shown in heavy lines inFig. 9. After the lug 26 has passed the arm 24, said arm swings into aposition shown in heavy lines, Fig. 9, where it will be engaged by saidlug on its return. The lug 26 is positioned on the rod 27 that said lugwill engage the arm 24 just before the auxiliary frame 15 has reachedits backward limit of movement, at which time the needles have beenwithdrawn and returned to their normal position. The lug 26 then engagesthe arm 24? and by means of the. shoulders on said arm and the link 24*,the links 24* and 24 are forced into the position shown in dotted linesin Fig. 22, thus tripping the dogs 23 and releasing the head block. Thehead block is then forced through the baling chamber past the dogs 23 bymeans of the action of the plunger on the hay within the chamber. Assoon as the head block is completely past the dogs 23 the steelspring-24 on the links 24 and 24 return said links to their normalposition, thus returning the dogs 23 to their normal position at whichposition they are again engaged by the next head block, for againstarting the mechanism in operation. The

arm 24 is so arranged that it will slide past the lug 26 before said lughas reached'its backward limit of movement and then swings into theposition shown in heavy lines in Fig. 9 whereby the same operation mayagain be repeated. After the plunger has traveled outwardly a certaindistance the dogs 32 are automatically disengaged from the plunger bymeans of the rollers 36 on the end of the arms 34- which arms arerigidly secured 9 to the frame 11 as best shown in Fig. 5, and theauxiliary frame 15- is then returned to its normal position by means. ofthe said springs 17 one of said springs being posi: tioned on the top ofthe main frame and the other on the bottom of said main frame, one endof each of said springs being secured to the main frame in any suitablemanner and the opposite end connected to said auxiliary frame. Duringthis outward travel of said plunger and before the dogs are released bymeans of the rollers 36,- the threading and binding operation isperformed, and during the inward travel of said auxiliary frame by meansof the springs 17 as above described the needles are returned to theirnormal position, the tying operation completed, the (logs tripped andthe head block released.

The mechanism by which the threading and binding operation is performed,I will now described.

There are two pairs of needles, one pair on each side of the framewhichneedles are pivotally connected at'their outer ends to the links 13 asbest shown in Fig. 5 and are provided at their inner ends with asuitable groove for holding a looped wire as best shown in Fig. 12. Asthe operation of both needles in each pair is the same, a description ofthe operation of one needle in each pair willbe sufficient for both,Referring to Fig. 5 and applying the same designation to the forward andrearward ends of the baling chamber as in Fig. 2 1 will designate thepair of needles which are on the forward side of the head block,thebinding needles,

while that pair on the rearward side of thev head block, I willdesignate as the threading needles. -With this understanding as toterms, 37 designates the binding needles and 38 the threading needles.

It may be assumed that the machine is in condition for operation, spoolsof wire 39 having been arranged on one side of the machine as shown inFig. 1 and the end of the wire in each case passed forwardly over therollers 40 and across the baling chamber to the clamp58 as best shown inFig. 5, and assuming that a sufficient quantity of bay has been placedin the baling chamber and the head block then placed therein, the wirewould then be in they position shown in Fig. 18. The ,plunger having areciprocatory movement forces the hay ahead of the head block and thehead block through the baling chamber and by means of the hay ahead ofthe head block the wire is forced into the position shown in Fig. 19.After the wires reach this position it is necessary. that sufficientslack be drawn into the. wire as shown in Fig. 20, so as to provide anendof sufficient length to reach back across the baling chamber and forma tie as shown in Fig. 21.

This is accomplished by the means new to .be

described.

Secured to one side of the frame 11 are brackets 42 on which is slidablymounted a vertical shaft 43 on which shaft is secured upper and lowerarms 44 which arms are provided with upwardly extending ends designed toengage the wire 41. Said shaft is provided at its upperend with a-shortarm .45 (as best shown in Fig. 10) designedto rest on the bar 46 whichbar is slidably mounted on the side of the frame 11 near one end and isslidably connected at its opposite end to a short arm 47. The arm '47--with a cam portion 46 which is designed" to engage the arm 45 and-toraise theshaft 43 when said bar is slid forwardly by means of the headblock engaging the lower end of thearm 47. lVhen the shaft is thusraised the arms 44 are necessarily raised upwardly and engage the wire41. After-the operation described above is completed thehead blockengages the lower end of the arms 48 by means of which the bar 48 ismoved .backwardly, thus causing the shoulder. 48

on the bar 48 to engage the arm 45 thus partly rotating the shaft 43 andthrowing the arms 44 out to the position shown in heavy lines in Fig.10. by means of which L the wire is drawn out of position as shown inFig. 20, thus providing sufiicient slack for extending the end of thewire across the baler and tying in the form shown in Fig. 21.

Pivotally mounted on the side of the frame 11 is a dog 50 (Fig. 11)which is designed to engage the notch in the bar 46 to prevent said barfrom sliding backwardly imtil the proper time. Immediately following theengagement of the dogs 23 by the head block 19 which moves the framerearwardly a short distance as before described,

-the lugs 33 on the rod 34 are caused to release the dogs 32 allowingthem to engage the-plunger 30 by means of which the auxiliary frame 15is drawn outwardly causing the needles and the arm 52 to travel acrossthe baling chamber. However, it is timed so that just as the arm 52 ismoved inwardly the dog 53 engages the pin 53 on the arm 54. (Fig. 42 andpulls the bell crank lever 55 ,inward y. By means of the rod 54 whichrod connects the arm 54 with the bell crank lever 55 (Figs. 3 and 4) thelink 57' which is pivotally connected to the fulcrumed levers 57 isdrawn upwardly thus opem'n the clamps 58 ("presently to be described andreleasing the wire therefrom. At the same time the lug 59 is forceddownwardly by which the dog 50 (Figs. 3 and 11) is released allowing thebar 46 to return to its normal position by means of the spring 60, thusreturning the arms 44 to their normal position by means of the spring 60on the shaft 43. This operation is completed just as the binding needlesengage the wire. To hold the wire away from the arms 44 when the shaftis returned to' its normal position, I provide the stationary springarms 61 which are rigidly secured at one end to theside of the mainframe11 by any suitable means s u'ch as the bolts shown (Fig. 2) and areprovided at their free or opposite ends with aflat surface on which thewire rests. Just preceding the releasement ofthe wires from the clampsthe movement of'the needles 37 are timed so that the ends of the needles37 strike the wire and carry it acrossto the twister, (presently tobe'-described). The end of the needle beinggrooved, and the movement .Ofthe needles 37 being timed to strike the wire before it isfully releasedfrom the clamps 58, a loop is formed in the wire which will prevent itfrom slipping over the ends of the needles as it is carried across tothejtwister. As the needles 37 are traveling across'the'baling chamberit is necessary needles 38 carry the end of the'wire leading 'that theclamps 58' remain open until the mamas from the spool to the clamps 58.For holding the clamps 58 open until this time, I provide a dog 61 whichis pivotally mounted on the .top of the frame 11 and is provided with anoutwardly extending arm 62 as best shown in Fig. i. It will be seen fromthis that when the clamps 58 are open for releasing the wire by means ofthe operation heretofore described, the lug 63 will be moved rearwardlysufficiently to engage the upper end of the bell crank lever by means ofwhich the clamps 58 are held in their open position and in whichposition they remain until the end of the bar 52 travels across thebaling chamber and engages the extending lug 62 on the dog 61 by meansof which the dog is forced out of engagement with the bell crank 55,thus allowing the clamps 58 to close. It will of course be understoodthat the mechanism is timed to be released and the clamps closed at thetime the end of the needle reaches said clamps so that the end of thewires may be clamped in place. The needles 38 start across. the balingchamber simultaneously with the needles 37 and it is therefore necessarythat just as the needles 38 engage the wire that the wire be cut-andheld on both sides of the place where cut. The end cut away (that is thewire going around the bale) is clamped in place and so held until theneedles 37 carry the opposite end of the wire going around the baleacross the baling chamber where the two ends are twisted, while theother end (that is the end leading from the spool) is clamped and helduntil the end of the needles 38 engage it and forces it out of theclamp. For accomplishing this I provide the arm 54 with a bifurcated-endas best shown in Fig. 4, in which bifurcated end is designed to travel abell crank lever 55 as best shown in Figs. 3 and 4, and when thebifurcated end of the arm 54 is moved inwardly by means of the arm 52the wire is clamped in place and cut by the means now to. be described.

Rigidly secured to the side of the frame 11 near the upper edge thereofis-an out wardly exten-tiing bracket 8i and pivotally mounted on theouter end of said bracket is the outwardly extending arm of the bellcrank lever as best shown in Fig. 3.

Pivotally connected to the bell crank lever 55 means of a suitable pinas best shown in l 'ig. 1+!- and are provided with 'a' beveled o:-sharpened edge as best shown in Fig. 4. When the upper end of the bellcrank lever 55 is moved inwardly by'means .of

the bifurcated arm 54 the link 85 is moved downwardly, thus forcing theinner or are two clamping devices which are positioned in a line withthe path taken by the wires 41 so as to engage the said wires whenoperated as best shown in Fig. 14*. As the construction and operation ofbothof these clamping mechanisms are the same a description of one willbe sufficient for both. These may be termed a compound clamp as they aredesigned to clamp the wire on each side of the blade. One of said clampsbeing held in closed position independent of the other and both beingdesigned to be closed or clamped at the same time. Rigidly secured tothe side of the frame 11 is a slotted casting 87 provided with jaws 88and is so positioned that the blade 86 is designed to travel in itsupward and downward movement in said slot. Mounted on the blade 86 is ajaw 89 designed to engage the jaw 88. The jaw\ 89 is provided at itslower end with an inwardly extending portion 90 'wl1ich is provided witha suitable opening through which is inserted a rod 91 which rod extendsthrough a suitable opening in the blade 86 at its upper end and isprovided at its lgwer end with a coil spring 92 and a suitable nut orrivet for holding said spring in place by means of which said jaw isconnected to the blade 86. The portion 90 .is provided with an arm93upon which is adapted to rest a slotted jaw 94 as best shown inFigs-14 and 14. The said aw 94 is slidably mounted on the casting 87 bymeans of the slot and pins as shown in Fig. 14. One of said pins isprovided with a cap 95 for holding said'jaw against outward movementwhile the pin 96 which is rigidly secured to the casting 87'holds saidjaw in its upright position. The jaw 94 is provided at its lower edgewith an inwardly extending portion designed to be engaged by thearm 93for forcing said jaw upwardly and clamping the wire in place. Rigidlysecured to the/lower inward extendingportion of the jaw 94 is a suitablerod which extends .dmvnwardly through a suitable opening in the arm 93and is provided with a coil spring and a suitable nut or rivet at itslower end for holding. said spring in place as best shown in Fig. 14. Asthe inner end I of the blade 86 i'snoved upwardly by means of thedownwardly movement of the link 85 as heretofore described the jaws 87and 94 are carried upwardly, thus clamping the wire between said jawsand the jaws 88 on either side of the blade as it is out. It isnecessary that the endof the wire is held between the jaws 89 and 88until the end of the needle strikes the wire and forms a loop (as bestshown in Fig. 15) for carrying the wire across to the opposite side. ,Byproviding the spring 92 it allows the wire to be forced out of the jawsby means of the needle but holds it sufficiently tight that a loop isformed before it is forced out. The jaws 89 and 88 are'held in a closedposition until the bar 52-has traveled inwardly suiiiciently fortheinner end of said bar to engage the arm 62 on the dog 61 thus releasingthe dog 61 from the bell crank lever 55 at which time the jaws 89 aremoved downwardly through the connection de scribed by means of thespring 52 (Fig. 4c) and at the same time the clamps 58 are closed by thesame means but through a connection presently to be described.

It is necessary that the bifurcated arm 54 j be disengaged from the bar52 after said bar has traveled inwardly a short distance. This Iaccomplish by means of the dog 53 j which dog is provided with a curvedarm 53 which arm travels in the path of the pin 56* which. engages thecurved arm 53 and forces it out of engagement with the pin -53 on thearm 54. When the bar 52 has returned to its normal position the spring53 returns the dog 53 to its normal position, in which position it isadapted to again engage the pin 58 on the bar 54.

It is necessary that the end of the wire held between the jaws 94 and 88should be.

held in a clamped position until the needles 37 have carried the wirefrom the opposite side of the baling chamber to the twister. This Iaccomplish by means ofa dog 97 which is pivotally mounted on a suitablesupport secured to the'side of the frame 11 and is designed to engage asuitable notch in the jaw 94 for holding it in a closed position, inwhich position said jaw will be held until the twisting operation iscommenced when it will be released by means .of the beveled lug on theperiphery of the wheel 66, which lug is designed to engage an arm on thedog 97 and forces it out of engagement with the notch in the jaw 94.

After the dog has been released from the jaw 9% the said jaw is returnedto its normal or open position by means of the spring shown.

The clamps 58 on the opposite side of the baling chamber which have beenheretofore referred to are two in number mounted one above the otherdirectly in the path of the needles 38. As the construction andoperation of both of these are the same a description of one will besufficient for both.

Rigidly secured to the side of the frame 11 is a casting 98 which isprovided at its upper end with a U shaped inwardly extending portionhaving bearing surfaces 99.

Slidably mounted on said casting by a means inverted U shaped portionsimilar to that in the casting 98 and having bearing surfaces 101 whichare designed to engage the bear- 100 is given a sliding motion withrespect to the casting 98 and by means of which the bearing surfaces 101are forced upwardly against the bearing surfaces 99 for clamping thewire in place. At the time the end of the needles 38 reach the clamps 58the end of the bar 52 reaches the arm 62 on the dog 61 thus disengagingthe said dog from'the pin 63 at which time the bell crank lever 55 isforced outwardly thus forcing the link 57 downwardly and closing theclamps by means of the spring 52 which spring is best shown in Fig. Byproviding the U shaped clamps 58 it permits the needles to be driven inand the wire clamped without clamping the needles.

After the free end of thebinding wires have been drawn across the balingchamber by the needles 37 it is necessary that these ends be twistedtogether with the ends cut from the wire leading from the spool by themeans above described. I will now describe the means and mechanism fortwisting these ends together.

Mounted on the side of the frame 11 opposite from the side on which theclamps 58 are mounted are two twisters which are mounted in a level withthe path taken by the wire and directly in the path taken by the needles37. As the construction and operation of both of these twisters are thesame, a description of one will be suflicient for both.

Secured to the frame 11 in any suitable manner is a casing 65 in whichis rotatably mounted a hollow cylindrical wheel 66 which is provided onits periphery with an annular groove for mountin the same in the casing65. The wheel 66 is provided with a stub shaft 67 which extendsoutwardly through a bracket 68 on which is securely mounted a gear wheel69. Mounted in the wheel 66 are a pair of pivoted jaws 7 0 which areprovided with diverging arms which diverging arms 71- extend outwardlythrough slotted openings in the stub shaft 67. Slidably mounted on thestub shaft 67 is a beveled collar 72 by means of which said jaws areopened and closed. For actuating said collar I provide a bell cranklever 73 which is pivotally connected at one end by means of a shortlink to the collar 72 and at its opposite end to a rod 74 which rod isprovided with lugs 75 and 76 as best shown in Figs. 1, 5, 6 and 7. Thejaws as shown in Fig. 6 are in a closed position and show the wiresstill being held after the twisting operation is completed memes andwhen the jaws are in this position the bell crank 7 3 would of course bein the position shown in heavy lines in Fig. 6. When the jaws are openthey will be in the position shown by dotted lines as will also the bellcrank 73. At the time the needles 3'? reach the jaws of the twister withthe end of the wire to be twisted it is necessary to provide means forclosing the jaws. For accomplishing this I provide a rack 7 7 which isrigidly secured at one end to the side of the auxiliary frame 15 andextends backwardly past the main frame 11 and is provided near itsrearward end with a series of gear teeth. Near its forward end issecurely mounted a lug 78 which is designed to en gage the lug 76 on therod 74 by means of which the collar 7 2 is slid outwardly on the shaft67,. thus opening the jaws 70 and releasing the twisted ends ofthe wire.During the time the lug 78 travels from the lug 7G to the lug thetwisting operation is performed by the means now to be described.Rotatably mounted on the bracket 68 is a gear wheel 79 designed to'meshwith the gear wheel 69. The gear wheel 79 is provided with the usualpawl and ratchet mechanism as best shown in Fig. 8. The small gear wheelis designed to be engaged by the gear teeth on the rack 77 as abovedescribed, both in its outward and rearward travel but by means of thepawl and ratchet device the large gear wheel 7 9 which meshes with thegear wheel 69 is only rotated during the backward travel of the rack 77by means of which the jaws are rotated and the ends of the wirestwisted. The mechanism is so timed that this twisting operation takesplace while the lug 78 travels from the lug 76 to the lug 75 as beforestated. It will be understood that the rack 77 is forced backwardly bymeans of the springs 17 which springs are attached to the auxiliaryframe 15 and the main frame as before stated. The jaws 70 are U shapedon the inside, so that the needles may be released and the wire retainedas best shown in Fig. 17. It will be understood that the jaws 70 arepositioned so that the wire coming from the spool and going around thebale passes between the jaws.

The head block 19 is provided with suitable transverse grooves as bestshown in Fig. 9 in which grooves the needles37 and 38 travel in crossingthe baling chamber and by means of which grooves the hay or othermaterial is kept from engaging the needles thus giving a clear andunobstructed path to the needles.

It will be understood that the auxiliary frame 15 may be provided withmeans for automatically connecting and disconnecting said frame with theplunger rod as will be done on some of the machines. in actual practice,instead of the plunger proper as shown a on its upper and lower sides Tolimit the backward movement of the i auxiliary frame 15 I provide stops103 which are rigidly secured to the baling chamber as best shown inFigs. 2 and 4.
